This is the reason I do not buy eggs that need to be shipped. I will drive 8 hrs one way to pick up the eggs first.
No matter how good the shipper package the eggs, the postal workers will screw them up.
One of my hatch buddies retired from the P O. She heard I was going to have some eggs shipped, I thought she was having a heart attack when she called me. Then she told me what some of the workers do with them and packages marked fragile. At the time she was working at the main shipping point in Marysville, Ca.
These pople actually play catch with these boxes and in some cses will walk on them.
NO SHIPPED EGGS FOR ME.
Read some of the past posts about shipped eggs. One person waiting for the eggs, saw the mail person coming down the road, as he drove by he throw the package out of the truck, hoping it would land on the proch.
